Morphology

subharmonic = harmonic (semi-transparent) = sub + harmonic

The formation 'sub-' + 'harmonic' is morphologically regular, but the precise technical meaning (a fractional relation rather than simply 'lower') is specialized and may not be obvious to general learners.

Etymology

Subharmonic combines sub- meaning 'below' and harmonic, from the same root as harmony meaning 'agreement of sounds'. So a subharmonic describes a lower vibration or frequency that fits the main tone because it is an exact fraction of it.
